RE: Flashing red light and no apparent coolant system cause, e.g., boiling, steaming, fan-running, etc., look to see if the fuel gauge, the clock, and/or the coolant gauge are erratic, or erroneous---- BEFORE you see the dealer. If they are, check the "voltage stabilizer" on the windshield side of the dash panel, under the removable hood.. It is mounted next to the clock on my 84 Westfalia. It should test 9.5 to 10.5 volts while the ignition is turned on. If it ranges above or below those numbers, it is faulty. (Bentley 90.4 Figure 2, "Voltage Stabilizer.") The part is about $12.00 at VW dealer, and the parts man as local dealer says it is common to VW products. Mine failed, and thanks to dagbear and Noto-Gaudette, my problem was solved by replacing the stabilizer, The main symptoms in my case were the flashing red light, "slow" clock, and the coolant level/temperature off the scale and no apparent coolant temperature range excess. Before replacing the voltage stabilizer, I checked the thermostat, flushed and changed the coolant (which the van needed), and, in general, hassled unnecessarily.

I posted, recently, this information. See the Archives.
